Answer:

20 hours

Step-by-step explanation:

If it is 1pm today and school holidays officially begin on Saturday at 9 amHow many hours away are school holidays?

The above question is quite short especially in details required to derive an answer

Now let's assume that the particular day been talked about is the day Friday,and we are now asked to find out how many hours away we are from holidays given that it(holiday) starts on 9am on Saturday .

If 24 hours make a day,and in the next 24 hours it will be 1pm on Saturday, then it means that we are less than a day away from this supposed holiday starting by 9 in the morning of Saturday.

All we now have to do is to subtract the number of hours 1pm to 9am to know the number of hours that we are looking for.

So,from 9am to 1pm is a difference of 4 hours,and we now have to subtract it from 24 hours to get 20 hours.

Answer:

95π

Step-by-step explanation:

area of a circle=πr²

radius of the big circle = 24/2=12

area of big circle = π(12)² = 144π

are of small circle = π(7)² = 49π

shaded area = area of big circle - area of small circle

= 144π-49π

= 95π

Find the discriminant, and determine the number of real solutions. then solve x^2 +8x+20=0

vodomira [7]

Answer:

Part 1) The quadratic equation has zero real solutions

Part 2) The solutions are

$x_1=-4+2i$ and $x_2=-4-2i$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}+8x+20=0$

so

$a=1\\b=8\\c=20$

The discriminant is equal to

$D=(b^{2}-4ac)$

If D=0 -----> the quadratic equation has only one real solution

If D>0 -----> the quadratic equation has two real solutions

If D<0 -----> the quadratic equation has two complex solutions

<em>Find the value of D</em>

$D=8^{2}-4(1)(20)=-16$ -----> the quadratic equation has two complex solutions

<em>Find out the solutions</em>

substitute the values of a,b and c in the formula

$x=\frac{-8(+/-)\sqrt{8^{2}-4(1)(20)}} {2(1)}$

$x=\frac{-8(+/-)\sqrt{-16}} {2}$

Remember that

$i=\sqrt{-1}$

$x=\frac{-8(+/-)4i} {2}$

$x_1=\frac{-8(+)4i} {2}=-4+2i$

$x_2=\frac{-8(-)4i} {2}=-4-2i$
